Which games had you beaten as a kid, yet now, you have no idea how you did it.

Jurassic Park [SNES]

You really needed a full day for this, it was completing a Dizzy game (for those old enough) where there is no save point, there is no mercy, you complete it beginning to end and it takes hours....

Oh, so this is a thing that happens to people? I have yet to figure out how I managed to beat the games I had on the Sega Genesis back in the 90s
Back then I even beat a good chunk of Revenge of the Shinobi (got up to "spiderman", not bad for a 9 year old), now I can barely get past the 1st stage in Sonic 2.

Currently stuck on Spyro 2, 2nd Boss Gulp (Reignited Trilogy) and the Speedways in all 3 games.
I cant do it. Dont know why. But i did them as a kid.
